This Vdriving clutch member is mounted on the shaft andsecured rigidly by the bolts 34 and is provided Vwith `clutch `engaging driving members 35. The end of the sleeve 25 adjacent to thesupport26 carries thedriving sprocket21 and when the sleeve 24 is thrust Aforwardly by pulling up on the rod 32 the clutch engaging `elements engage and transmit power from the shaft B through support 24, sleeve 25, sprocket 21, belt 22 and sprocket 2O to the pump shaft 19.

the lower surfaceof'the combined cylinder Y end and support 10: by m'eans of the bolts 41. This rectangular frame has one of its sides 42 formed Vwith a depending plate 43Y upon the outer side of which the pump 'casing 12'is secured by bolts 44 at a suitable distance from the main drive shaft B so ,that the belt 22 may operate efiiciently over i Ythe sprockets 20 and 21 and be sufficiently casing.

close so that a compact structure is produced. The skeleton frame ofthe manifold bracket is formed with a duct 45 connected withY the port 46 in the combined lower end and support 10 of the cylinder leading upwardly into the cylinder and at its lower end with the port 13 inthe side of the pump casing. This duct extends downwardly below the 'cylinder then turns to one side and again downand out through the side of plate 43.- The sides of the frame of the manifold and the duct also extend forwardly to most effectively position the pump The manifold bracket is also formed with Aa` reinforcing wall 50 within its rectangular walls which unite with said rectangular'w'alls and with the duct-45 to reinforce the vstrength of the entire struetureA with a minimum amount of material. TheV lower side 47 of the manifold bracket forms a support for the flanged upper end 48 of theY clutch holding element 26 to which it is secured by the bolts 49. Thus the maniv fold bracket produces a unitary structure with a minimum amount yof material vfor supporting the pump, clutch and clutch actuator below the hoist cylinder in compact form and. a connection between the pump and l cylinder for the transmission of the compellin-gliquid, said parts being arranged so thatvthe pump may bedriven by the drive shaft of the vehicle and so that the valvemechanism of the pump and clutch shifter maybe manipulated from above the base Vand end of the cylinder.

In accordancewith the patent statutes I have described the principles of operation of my invention together with the apparatus which 'l now consider to represent the best. embodiment thereof, but I desire to have it understood that the construction shown is only illustrative and that the invention can be carried out by other means and applied to uses other than those above set forth within the scope of the following claims.

Having described my invention, what I claim as new and desire to protect by Letters Patent is 1..In combination with a hoist cylinder, a' drive shaft disposed below said cylinder, a clutch mounted upon said shaft, a pump arranged at one side of the shaft having operating connection with said clutch and a clutch actuator, amanifold bracket having members arranged to support said pump, clutch and clutch actuator in said position and a duct in said bracket leading downwardly from said cylinder into the side of said pump.

2. In combination with a hoist cylinder having a drive shaft arranged below the cylinder, a pump arranged at one side of said drive shaft, a clutch mounted on said shaft and adapted to be connected with said pump to communicate power from the shaft to the driving member of the pump and a clutch actuator associated with the clutch for moving the clutch into and out of clutch engaging position, a manifold bracket secured to the lower end of said cylinder, said bracket being formed with a' depending plate on one side t o which said pump is attached and with a duct therein leading from the. lower end of said cylinder into Vsaid pump for the impelling liquid, said bracket being formed with a forwardly projecting lower end upon which said clutch and clutch actuator are mounted.

3. A manifold bracket for the cylinder and pump ofa hydraulic hoist, consisting of a skeleton frame having a forwardly projecting lower end and sides, a depending plate from one of said sides adapted to forni a support for the pump and a duct leading downwardly through said frame and lat@ erally through said lower side, adapted to form a communication between the pump and the cylinder of the hoist for impelling liquid.
